SmartCursor Cues

The following table lists the individual cues that the SmartCursor uses along with a description of each. In many cases, two cues are used together to indicate that two constraints have been activated. For example, the cue ‘Align H/Angle’ means that the point located is both aligned horizontally to the indicated snap point and also constrained to an angle.

Some cues display when a first point has already been found, and a second point is being sought. These two points form a line called the feedback segment. This segment forms an angle and length which the SmartCursor uses for some of its snaps.

For a line, the feedback segment is the same as the line being drawn. However, for other objects, the interactive image does not lie on the feedback segment. The SmartCursor always works on the feedback segment created from the first to the second points.
